Best street tires?

If you are staying with 14" or 15" wheels I don't think you will find anything better than the BFG Radial T/A. If you go bigger on the the rim then you open up a world of tire choices.

FWIW, I have 215/60-15 on the front and 255/60-15 on the rear of my 68 Cuda and for a fair weather daily driver I am quite happy with the tires.
